Problems solved by technology

However, under realistic conditions, the devices used are not perfect, and its influence on the minimum entropy is difficult to quantify in the model, making it very difficult to accurately estimate the minimum entropy. At the same time, the imperfect characteristics of the device are easily exploited by hackers , resulting in a safety hazard

Abstract

The invention discloses a quantum random number generator independent of measurement end devices. The quantum random number generator includes a credible random source and an incredible measurement end; the credible random source randomly works in a random number generation mode and a safety verifying mode; in the random number generation mode, the credible random source sends a fixed quantum states to the incredible measurement end, and the incredible measurement end performs measurement; in the safety verifying mode, the credible random source sends different quantum states to the incredible measurement end, real-time safety verifying is performed according to a measurement result output by the incredible measurement end, the minimum entropy of original random data is estimated according to the measurement result, and random numbers independent of the measurement end devices are generated. The scheme of the invention can effectively eliminate potential safety hazard due to incredibility and imperfection of measurement devices.

Description

technical field [0001] The invention relates to quantum random number generation technology, in particular to a quantum random number generator irrelevant to devices at the measurement end. Background technique [0002] Random numbers are a widely used basic resource, and have extensive and important applications in many fields such as quantum communication, cryptography, gaming, Monte Carlo simulation, numerical computing, random sampling, neural network computing, and traditional information security. The randomness of the quantum random number generator is derived from the basic principles of quantum physics. Compared with the traditional pseudo-random number generator and noise source random number generator, the source of its randomness is clearer, and its randomness can be strictly proved by using the minimum entropy theory. , and can generate true random numbers with a series of basic characteristics such as unpredictability, non-reproducibility and unbiasedness.
